Explanation:
Deformation of the crust,...That's what happens when Earth's crust gets all squishy and changes shape! There are different types of crust deformation, including folding, faulting, and uplift. Imagine if you took a piece of playdough, pressed it flat, and then twisted it, stretched it, or folded it over. That's kind of like what happens to the earth's crust, making mountains, valleys, and even earthquakes!
